BUTTON.

SPECIFICATION forming part of Letters Patent No. 636,960, dated November14, 1899.

Application filed August 29, 1899. Serial No. 728,923. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. DOVER, a citizen of the UnitedStates,residin g at Oranston, Providence county, and State of RhodeIsland, have invented a new and useful Improvement in Buttons, of whichthe following is a specification.

My invention relates to that class of buttons in which the use of solderis dispensed with; and its object is to secure a maximum stiffness in abutton without increasing the weight thereof, which end I secure by thenovel arrangement of parts disclosed in the accompanying drawings, inwhich- Figure 1 is a perspective view of my button shoe and post Fig. 2,a plan view of the head pieces; Fig. 3, a side view of the post with thehead-pieces applied thereto; Figs.4 and 5,perspective views of thebutton parts after the setting-up operations. Fig. 6 is a plan view ofFig. '5, and Fig.7 a vertical sectional view of completed button.

Similar letters refer to similar parts throughout the several views.

To the hollow tapering post a of my button I apply two concavo-convexplates 19 c, Fig. 2, in such a manner that the periphery of the lowerplate 0 contacts with that of the upper plate I), which latter platediffers from the former in that it is pierced centrally with an angularopening rather than with one circular in form, as shown in plate 0,which prevents the plate I) from turning on the post. The parts nowpresent the arrangement shown in Fig. 3, wherein the top of post a(lettered d in said figure) projects some distance beyond the plate 1).I next enlarge the cylindrical projection 01 by the downward stroke of apyramidically-shaped tool to the form shown at d, Fig. 4, and by asecond downward stroke with greater force press the material outwardlyuntil it rests closely upon the plate I), as at d, Fig. 5, to whoseupper contour it conforms. I complete the button-head by applying aface-cap e in the usual manner. It will be seen that the resultingbutton has-a great degree of stiffness, due to the mutual relations ofthe parts, which are so disposed as to distribute the strain brought tobear upon the button-head, the lower head-plate being held in place byfriction with the post, which friction is increased by any force appliedto the post, whose laterally-projecting extremity tends to force theupper upon the lower plate. Thus all the parts reciprocally unite tostiffen the button.

I am aware that prior to my invention buttons have been made without theuse of solder to unite their parts. I therefore do not claim thisfeature as my invention' What I do claim as my invention, and filesireto secure by Letters Patent, is

1. A button comprising a tapering post, two concavo-convex plates withtheir convex sur faces outermost each secured to the post, and

r a third plate extending over the upper of said plates constituting aface-plate.

2. A button comprising a taperingpost, two concavo-convex plates withtheir convex sur faces outermost secured to the postby lateralprojections extending from the post upon the outer surface of the upperplate, and a faceplate extending over the upper plate.

3. A button comprising a tapering post, two concave-convex plates withtheir convex surfaces outermost secured to the post by lateralprojections extending from the post upon the outer surface of the upperplate, and a faceplate extending over the upper plate and bent in underthe outer edge of the lower plate.

4.. A button comprising a tapering hollow post, two concavo-convexplates with their convex surfaces outermost carried by said post, theupper of said plates having an angular opening through which the postpasses, projections extending from the post upon the outer surface ofthe upper plate, and a face-- plate extending over the upper plate.

In testimony whereof I have subscribed my name to this specification "inthe presence of two witnesses.-

GEORGE W. DOVER.
